niesonotuui finely striate in front, alutaceous behind. Epinotum 

 transversely striate. Abdomen alutaceous, with a slight silky sheen. 

 Nodes of petiole posteriorly, transversely and minutely striate. 

 Clypeus and frontal carinae longitudinally striate. Head quadrate, 

 only very little longer than wide. Pronotum exposed only at the 

 shoulders, which are rounded. Mesonotum one-third longer than 

 wide ; scutellum a little more than one-third the length of the meso- 

 notum. Epinotum more deeply excavated than in the $ , so that the 

 margins at the junction of the declivity and dorsum form a distinct 

 and elongate boss on each side. Nodes as in the $ , but the 1st is 

 more compressed from back to front, and its front face is more vertical 

 and flatter than in the £ . Wings pale smoky yellow ; nervures pale 

 brownish yellow.

^ . 3 mm. Dark reddish brown, the pro-mesonotum a little redder ; 

 mandibles, antennae and legs dark brownish yellow. Head slightly 

 shining, microscopically reticulate-punctate, between the frontal 

 caiinae finely and longitudinally striate. Thorax and posterior faces 

 of the nodes dull, closely reticulate-punctate, the sculpture stronger on 

 the nodes than on the thorax. Abdomen smooth and shining. Head, 

 excluding the mandibles, very little longer than wide ; the posterior 

 angles rounded, as wide behind as in front ; the posterior margin 

 almost straight or very feebly concave. The scape not extending back 

 to the posterior margin by a distance equal to the length of the eye. 

 Median area of clypeus with very indistinct carinae, the space 

 between very shallowly excavated. Thorax decidedly narrowed at 

 the meso-epinotal suture ; dorsum of epinotum not quite half as long 

 as the pro-mesonotum, a little longer than wide ; the declivity is 

 short, and forms a rounded but fairly distinct angle with the dorsum. 

 Second node of petiole a little wider than long, hardly wider than the 

 1st, narrowed posteriorly. A very scanty pilosity on the nodes and 

 abdomen. 



" ? . 6 mm. Head a little wider than the thorax. Entirely dull ; 

 colour as in the ^ ." 



"^. 47 mm. Entirely black. Wings hyaline. Mesonotum alto- 

 gether dull. The erect pilosity moi-e abundant than in the type of the 

 species. Elagellum brown ; tibiae and tarsi pale yellow."
